The mode of initiation, the use of the same symbols, with an identical signification ascribed to them, by peoples living so far apart whose customs and manners were so unlike, whose religion, so far at least as external practices were concerned, differed so widely, show that these mysteries originated with one people, and were carried to and promulgated among the others. As we do not find it mentioned anywhere that they originated either with the Egyptians, Chaldees, or Hindoos, and we have seen that their primitive traditions have been derived from the history of the early rulers of Mayax, is it not natural that we should look for the institution of the mysteries among the Mayas, since we find the same mysterious symbols, used by the initiates in all the other countries, carved on the walls of the temples of their gods, and the palaces of their kings? Their history may afford the clue to the original meaning of said symbols, as their language has given us the true signification of the words used by the celebrating priest to dismiss the initiates in the Eleusinian mysteries, or by the Brahmins at the end of their religious ceremonies, and as it has revealed the so long hidden mystery of the mystical TAU. That sacred mysteries were celebrated from times immemorial in the temples of Mayax, Xibalba, Nachan (Palenque of to-day), Copan and other places of Central America there can be no doubt, since besides the symbols sculptured on the walls of the temples and palaces, in two distinct instances, we see the rites and the trials of initiation described in the Popol-Vuh; and as these rites and trials were identical with those to which the applicants to initiation in the mysteries of Egypt, Greece, Chaldea and India were subjected, we are justified in seeking in Mayax for the causes that may have induced the founders of the sacred mysteries to select the odd numbers 3, 5, and 7, instead of the even 2, 4, and 6 for mystic numbers.
